* Force of Gravity Depends on Mass and Distance: The force of gravity between two objects depends on the mass of each object and the distance between their centers. The greater the masses, the stronger the attraction. The closer the objects, the stronger the attraction.

* Missing Information: You haven't told us what the mass of the "5" is. Is it 5 kg? 5 grams? 5 tons? Without knowing this, we can't determine the gravitational force.

Let's break down the problem:

1. The 10 kg object has a greater mass than the unknown "5" object. This means it contributes more to the gravitational force.

2. The distance between the objects is 1 meter. This is a relatively small distance, which increases the gravitational attraction.

Conclusion:

We can't say for certain if the 10 kg object has the greatest force of gravitational attraction without knowing the mass of the "5" object. If the "5" object is extremely massive, it could overcome the 10 kg object's greater mass, even at a closer distance.

To get a definitive answer, you need the mass of the "5" object.
